Dental hygiene has come a long way since this post! Pepsodent (The Delineator, May 1917):

This one kind of surprised me. How about you? Underwood Deviled Ham (Ladies’ Home Journal, June 1917):

And this ad takes this week's prize for inventiveness. I thought "Oh, chewing gum saved a pilot's life by helping him stay awake...but no, nothing so prosaic.

Wrigley’s Gum (The Red Cross Magazine, August 1917):
